TITLE: 01/19 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Camilla
SHIFT SUMMARY: Eq lockloss, then trouble with ALSY
LOG:
14:18 Lockloss caused by high microseism and earthquake seismic transition

I spent the next hour waiting for the ground to calm down, then waiting for ALS locking to fail. I could help lock the X arm after waiting for way too long, but no real visible light on the ALSY camera. I know this is a problem we've run into before, but couldn't find the fix in either Jenne's troubleshooting document or the alog, or even the H1 troubleshooting ops wiki. The only clue I have is that when the Xarm is locked the green wfs qpds have spots that are centered and the yarm A qpd doesn't have a spot and the B is not centered.
